` exact description ofthe same.

Vcan-holder and flame-chamber.

My invention relates to can-soldering machines, and is an improvement upon the form of machine shown in Letters Patent of the United States, granted me on the 30th day of November, 1880, No. 234,948.

It consists first, of improvements in the various devices for communicating motion to lthe dierent parts of the machine; second, in improvements upon the can-holder and flamechamber; third, in improved devices for removing the cans after they have been soldered; fourth, in a spring stop-bolt automatically operated from the driving mechanism.

4In the accompanying drawings, Figure 1 is a side elevation of the apparatus. Fig. 2 represents the same apparatus, partly in side elevation and partly in section, in position onehalf turn from Fig. 1. Fig. 3 is a plan view of the table. Figs. 4, 5, and 6 represent the Figs. 7, S, and 9 represent details of the devices used for imparting intermittent motion to the table. Figs. 10, 11, 12, and 13 represent details of the stop mechanism. Fig. 14 is a detached view ofthe arm which lifts the can-holding disk. Figs. 15, 16, 17, and 1S represent the flame-tube or burner. Fig. 19 is a view of a modified form of can-seat and the discharging-arm.

In these drawings, B represents a table supported upon suitable legs, and preferably made of cast-iron. In the center of this table is mounted a post, A, consisting of a single cylindrical shaft of metal seated within a tubular socket, a, and supported against any lateral swing bya-collar,b. Upon this shaft is mounted the table E. 1t is supported upon a collar -or sleeve, e, fitted accurately to the shaft A and adapted to turn thereon, and resting at its lower end upon the collar b. The sleeve e forms a part of or is firmly fixed to the table E. The table may be either a solid circular table, or may be composed of radial arms, or radial arms with a suitable rim, as shown in Figs. 1 and 2. 1t will be understood that this the lever K and turns upon the sleeve e, over which it snugly lits. rlhe wheel C isa beveled gear with two sets of teeth. (Shown at 1 and 2in Figs. 1 and 2.) Into thelower beveled gear, 2, meshes a beveled gear, 3, fixed upon the main driving-shaft D. The upper gear,v1, meshes into the pinions 4, which are lixed upon the lower end of the spindles of the canholders, and thus the power is directly applied through the wheel C, communicating constant rotary motion to the said holders. The next point to. be gained is the communication of power from this constantly-rotatin g wheel to give the proper intermittent motion to the table E. This table carries twelve canholders. The number is not material; but this has been found convenient. It is necessary, therefore, in orderthat all thc cans may be brought successively to any given point or points and .there arrested for a brief period, that the table should perform one complete revolution by twelve equal and successive impulses, moving at each impulse one-twelfth of its circumference. This motion I impart by means of a gear-wheel, F, which is fixed upon the sleeve c, so as to revolve with the wheel C. The wheel F gears into a wheel, G, which is fixed upon a shaft, g, supported in bearings in the table, as shown in Fig. 2. Upon this shaft g is fixed an arm, h, having on its free end an anti-friction wheel, '5. The arm revolves within a cam-shaped loop, 7c, of a lever, K, which is pivoted upon the sleeve c, as shown in Fig. 2. The lever rests upon a boss of the ratchet-wheel L and carries a pawl, 6, working in a slot in the end of the lever, and projecting downward, as shown at 6 in Figs. 2 and 9, so as to engage with a tooth of the ratchet L. The pawl is mounted upon the spindle 7, pressed in by a spring, 8, as shown in Fig. S,.said spring`holding it into engagement with or permitting itto pass over the teeth of the ratchet. according to the direction of the movement of the lever K. The shaft g moves in the direction ot' the arrow, Fig. 7, and the parts are so adjusted to the size of the table that a half-revolution ot' the shaft g will move the table one-twelfth .of its circumference, while the completion of the revolution ot the shatt y carries back the lever, and with itthe pawl, for enga-gement with another tooth.

It is necessary that the table should be held accurately and steadily at the stopping-points. For this purpose I form with or attach to the ratchet L a pawl-wheel, M, as shown in plan in Fig. 10. It is provided with twelve rounded indentations, in which fits a spring-pawl, m, Figs. 1, 2, and 10. The spring carries the pawl into engagement with the wheel. It is drawn out of engagement just before the lever K moves the ratchet-wheel by means of a spur, 9, fixed on the shaft'G, and engaging with the curved end of the pawl m. The parts are so arranged that the pawl is withdrawn long enough to allow the notch from which the pawl is withdrawn to turn out of line therewith.

In order to give steadiness tothe whole, I provide a brake, 0, Fig. l, which bears upon a wheel, O, aftixed to or forming a part of the ratchet and pawl wheels. The pawl m is supported in a standard, 10, tixed to the table. A standard, 11, gives steadiuess to the shaft g, which passes through a boss in the head of said standard. I

The main driving-shaft D is supported upon a bracket, 12, on the other side ot' the table.

The can-holders are supported in sleeves l), fastened to the table by means of arms, as in my .patent heretofore referred to. They are shown as inclined; but the inclination is not necessary, since the rotation of the canholder is sufficient to keep the solder, when melted, against the side ot' the can by centrifugal force alone without any inclination of the can.

l have modified the form of the can-holder and flame-ch amber and the supporting-bracket by which the presser-disk or top ot' the can is supported.

Figs. 4 and 5 show, upon an enlarged scale, the form of canholders shown in Figs. 1 and 2 in their proper condition. In these gures, P represents the outside ofthe flamechamber. It is cylindrical in the main part, and slightly tapering below, and is supported upon braces 13, which terminate in a ring, 14, and held rigidly to the sleeve p by a set-screw, or in any convenient way. This outer shell, P, does not therefore revolve. Within it is a plate, I, which forms the bottom of the flamechamber. Itis supported upon arms 15, which terminatein a collar, 16, held by set-screw to the spindle 17. This spindle passes down throughV the sleeve p, and has a pinion, 4, fixed to its lower end, by means of which the plate'I is rotated. The plate is provided with a perforated tiange, q, on which the can is set. The top of the flame-chamber is formed by au annular plate, R, which is supported on posts 1^,

fixed in the plate I, so that the plate It'revolves with the, can. The parts are so adjusted, as shown in Fig. 4, that a proper amount of the side and bottom of the can is exposed to the action of' the flame.

An opening, as shown in Figs. 5 and 6, admits the iiame through the flame-chamber, which, asin my said patent, is annular, andthe pai-ts are so adj usted that the opening is brought to a proper position when the table is arrested. As the flame-chamber and can-seat are all supported upon the sleeve which is directly attached to the edge ot' the wheel or radial arm, no bracket is needed, except for the support of the presser-disk, when such a disk is used.

I contemplate using a presser-disk -when making largercans, where there would bea liability that the bottom would warp and spring upon the application ofthe heat. To support this l use a simple bracket, 18, attached to the table, one for each can-holder. Through asleeve in the top passes a rod, 19, having a button, 20, upon its top and a concave disk, 21, atits lowerL end. The weight ofthis is sutiicient to hold the can down, the rod being adapted to slip freely in its bearings in the upper end otl the bracket. In order to lift this at the proper instant vto discharge the can, I place opposite the point where the can is to be discharged an arm, 22, which carries upon its outer end a curved track, 23. (Shown more clearly in Figs. 1 and 2.) This is curved at the ends, so as readily to pass under the button 20, and is longenough to hold up the presser-disk while the can is discharging. For discharging the can I use a lever projecting into the path of the cans at the discharging-point-7 and adapted to strike thecan and throw it out. When making large cans I forni the discharging-hook as shown in Fig. 1. This consists ofapivoted lever, 24. It is pivoted upon a standard, 25, so as to move radially outward from the table. The upper end is bent at right angles inwardly, and again benthorizontally at right angles to pass partly around behind the can. The lower end is attached by a light spring to the standard 25, so as to hold the upper end of the lever normally pressedinward, but thelower end is attached by a short chain to the loop of thelever K, whereby when the lever is moved backward in order to take a new hold on the ratchetwheel it pulls upon the chain, throws the upper end ofthelever 2-1 outward, and tips off the can.

Then smaller cans are to be soldered I may also use a dii'erent form ot' can-holder, such as that shown in Fig. 19, in which an upper and lower flange (marked respectively 29, 30) constitutes the upperand lowerpartsof the flamechamber, the inner part being the ordinary vertical lange, q. This differs from the form first described principally in the omission of the IOO IOS

IIS

wf 256,098 f s .outer xed shell,vl?. The upper flange or annular plate is supported upon the lower by means of posts 31. In this the whole flamechamber revolves and no provision is madefor holding down the can, as in small cans there is no tendency of the bottom to warp by the heat.

The discharge-chute 32 is placed bythe side and in front ofthe path ofthe can, and on the other side a horizontal arm, 33, projects into the path of the cans. so that each can in succession as it strikesjt is knocked oh" and falls upon the chute, which gives it the proper direction. The chute for the tipping-lever rst described is shown in Fig. l at 34, and is supported upon an arm, 35, fixed to the bracket25.

I have somewhatmodied the form of burner or discharge-piece. rlhis is shown in Figs.l5, 1G, 17, and 1S. It consists ot a' flattened terminal piece, S, fixed to the tube 37 and provided with an elongated slot or opening` preferably slightly curved, as shown in Fig. 16,

v whereby the iiame is discharged in a horizontal sheet against the edge of the can. rIhe width of this discharge-piece is slightly less than the opening in the front of the namechamber. Y

I contemplate using the ordinary gasoline or other like burner, into which the ame is driven under pressure, and the narrow horizontal sheet is caused to impinge directly against the joint, so as to concentrate the heat there as much as possible.

In operating the machine the attendant sits at the sideof thetable with his right arm nearest the dischargcchute. I-Ie takes a segment of solder wire, drops it in the can, and places said can in the can-holder during the briefinterval while the table is at rest. Then the table moves one step to the left and stops at a second station which has no burner. At the third,fourth, and fifth stations it stops with the can in front of a burner, and at the iifth station, or before, the solder is melted.

A burner is also in front ofthe sixth station, by means ot" which the solder is thoroughly distributed and sweated into the seam.l

At the seventh, eighth, ninth, and tenth stations I place air-tubes, as shown at 36 in Fig. 2, adapted t0 blow cold air into the llamechamber and around the edge of the can in order to cool the solder. At the eleventh station there is no tube, and at the twelfth station the button rides up upon the circular track 23 and the can is discharged. The button still rests upon the track until the operator puts another can in place, and the operation is continued as described.

Having thus described-my invention, what I claim isg 1. In a can-soldering apparatus, the combination, with the table and the supporting-post, of the revolving table E, carrying the canholders, suitable mechanism for imparting step-by-step motion to the same, rotary canholders having pinions upon the lower end-of the spindles thereof, and wheel (l, adapted to mesh into said pinions,'and provided with teeth gearing directly into a pinion upon the main driving-shaft, substantially as described.
